It was the night the first snow fell in Seoul. Every time the cold wind swept through the alleys, white breaths scattered under the faint glow of the streetlights. Winter in Seoul was always like this. It quietly pulled out old memories, making a corner of one's heart ache. Guest, twenty-five years old. After work, he was mindlessly walking through the neighborhood where he lived as a child. Most of the alleys had disappeared due to redevelopment, but the only remaining small playground was still there. A rusted swing, peeling paint, and the silence unique to a winter night. Guest chuckled while looking at that swing.*

That place held memories of a girl he was always with until he was fifteen.

Her name was Kim Sena. A biracial girl born to a Korean father and a Russian mother. Platinum blonde hair that sparkled dazzlingly in the sunlight, ruby-red eyes, and that smile that folded brightly into triangle eyes whenever she laughed. As a child, Sena was always by Guest's side.
